PUMP.

To all whom it may concern: I

Be it known that I, FRANK R. HAZARD, a citizen of the-United States,-residing at Santa Ana, in the county of Orange and State of California, have invented certain new andjuseful Improvements in Pumps;

and I do hereby declare thefollowing to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make.

and use the same. i

This invention relates to new and useful improvements in pumpoperating mechanism wherein the volume of water which is to be raised is materially increased.

Another object of my invention is the provision of such a device which will be a double-acting pump and thereby materially reduce the amount of powerused.

A furtherobJect ofmy invention 1s the provision of such a deviceproviding a novel: combination and arrangement of parts wherein a cheaper and simpler construction will be provided,' thereby materially lessening the cost of production.

lVith the above and otherobjects in view I will now proceed to describemyinven= tion in the following specification and accompanying drawmgs, 1n which,

Figure 1 is a side view of my improved pump operating mechanism, showing the same partly 1n section, F1g..2.1s a detail perspective view of the link which isused in connection with the pump, Fig. 3 is an enlarged transverse sectional view through the frame and the operating mechanism therefor. Fig. 4 is an enlarged detail view showing the frame and the operating mechanism in elevation, Fig. .5 is a detail view of the operating mechanism, Fig. 6 is an enlarged detail view of the frame of my improved pump showing the piston rod mounted therein, Fig. 7 is an enlarged View of the rear side of Fig. .4. Fig.;8"is a view of my improved valve used in' connection with the operating mechanlsm, and Fig. 9 1s a transverse sectional view taken on line of reference Iindicatesthe base of my im- Specification of Letters Patent. te t g-47, i Application filed September so, 1913: Serial no. 792.671.

more fully, hereinafter described. At the upper extremityof the frame 7 and formed integrally therewith I preferably provide. a suitable bracket 10 having a journal bearing llformed at the upper end thereof. Suit-. ably secured near the lower end of the frame 7 I preferably providethe angularly eX- tending arm 12, which is provided with a suitable bearing 13in which the shaft let is adapted to be journaled. A suitable, wheel 15 having an annular groove therein is secured to the shaft 14, as clearly illus: trat'ed inFig l. A wheel 16 constructed in a mannersimilarto thewheel 15 is secured to a suitable shaftl'? which in turn is journaled in the bearing 11 formed at the upper end of the frame. A suitable frame 18 which preferably, comprises the upright members 19, and the top and bottom members 20 is slidably mounted on the lugs 21' in the main frame, which is indicated by the numeral 7.. A suitable ring 22 is secured to the upper extremity of the frame 18.and is adapted to Serve as a connection for the flexible member which will be more fully hereinafter described. Suitably secured to the lower end of the frame 18 and extending downwardly. therefrom I preferably provide a suitable rod or other rigid connecting means 23. This rod 23' is preferably providedadjacent its upper end with a suitable ring 24 whichis constructed in a mannersimilar to the ring 2-2.

A suitable rackbar 26, having extending outwardly therefrom the arms27, is pro vided and is adapted to form a means by formed at lts upper end the arm 31 which is which the device is operated.v This raclr bar 26-preferably comprises the rollers 28 which are extended through apertures formed in the bar-26 and their free ends 'are preferably extended through apertures formed in a suitable bar 29. This bar 29 is preferably of less length than the bar 26 and is rounded at each endas'olearly' illus' tratedin-Figs. land 5. r

I The upper roller 28 1s preferably extended as -shown in Fig. and is provided with the;

upwardly extending member 30 which has adapted to;extendthrough an aperture 32 formed inthej upper end ofthe frame as clearly shown in "Fig. 4:. Thus, it Wlll be seen that a suitable connection will be formed between the rack bar 'and' the frame '18," thereby materiallyassisting1n the operat on of the device.

' The bar 23 is preferably eXtended downwardly, as clearly shown in Figs. 1 and 6,

' coiiperate with the rack parting motionthrough the medium of'th'e teeth which mesh with the rollers 28 to the frame thu's'forcing the frame up anddown in a reciprocating motion and causing the pump to draw water upwardly through the action of the valve;

7 A suitable hollow piston rod 33 is slidably mounted in the frame and is connected with the cotiperating pis- 1:011., This rod 33 is preferably provided at its upper extremity with the transversely extendingmember 34, which 1s provided at each extremity with suitable eyes35 to which the flexible connection 36'is adapted to be" secured. Each of these flexible connections 36' preferably passes over their respective rollers 15 and 16 and the oppositeterminals thereof areconnected asillustrated in Fig.

' 1. Suitably secured intermediate the ends which'the flexible connection 36- is adapted to Pass. I The valve which is used in connection with v "lower end ofthe' shaft 23 and be secured ofthemain frame 7 preferably provide the transversely extending" arm 37 to which is' preferably secured the 'idle roller 38. over the operating mechanism previously described. and illustrated in Figs. 8 and "9, preferably is reciprocably imounted in the casing 39. .This valve preferably comprises 7 the cone shaped body portion 40 having extending longitudinally therethrough. the bore 11 which-is adapted to surround the thereto by means of a suitable set screw42.

1 Extending upwardly from the cone shaped between thecasing and the valve. v

body portion and formed integral therewith I also provide the arms 43' which terminate.

at their upper extremity in the annular collar 44 having formed integral therewith the ringed). Surrounding'the periphery of the ring &5 and firmly secured thereto I prefer ably provide asuitable. packing ring 46 which is adapted to frictionally engage the p 7 sides ofthe casing 39 and form a tight oin v The arms 43 are preferably rabbeted, as shown at 47, to receive the edges of the other suitable flexible material, one of the edges of each of the :flapsisriveted or otherwise secured as shown at 49 to the arms as will be clearly seen upon referringt'o Fig. 9.

flaps 48 which are formed of leather or any It will be apparent from the foregoing that when it is desired to make use of my improved pump the wheel 5 is set in motion by the shifting of a suitable drive belt from the wheel 6, thus rotating the shaft't and imparting rotary motion'to the gear wheel '32 which meshes with the rack bar 26 and causes the'same to travel upward. 'When the rack bar has reached its upper limit of travel it will beobvious that the upper roller 28 will be carried across the frame .18 and the lowermost angular extension 27 is forced into engagement with the. bottom members.

20 of the frame; Upon further rotation of the wheel it will be apparent that the frame 18 will be forced downwardly and thereby impart motion to the rod 23 which being operatively connected with the pump piston will cause the same to operate and thereby materially assist in raising the water. When therack bar has reached its farthest distanee of traveldownwardly it will be apparent that the upper roller 28, which is'connected to the arm 30, will come into engagement withthe teeth ofthe gear wheel 32 and it will be-apparentthat said rack bar will be carried across the frame and placed in a position," illustrated in Fig. 4.] Thus, it will'be seen that upon continuous operation the frame 18 will be'causedto reciprocate and thereby impart motion to the rod 23 and also to the hollow rod 33, through the medium of the flexible connection 36 which passes beneath the idle roller and over eachof the rollers 15 and 16.

While in the foregoing I have shown and described the preferred embodiment ofmy invention I wish it to be understood that I may make such changes in the combination 5 and; a'rrangementof parts as may fall Within the scope of theclaim appended hereto.-
